Ignition, voltage and car not starting issue

[smiths0n]

HELP!!!! Electrical issue!!!

Context, so the voltage wasn't showing 12volts when in ignition or 14volts when running, struggling to start so thought battery was low. Even when jump starting or a battery connected in series didnt allow the volt gauge to read correctly either. Volt gauge is attached to the radio wiring.

Thought alternator was the issue as when revving it did nothing to the voltage reading either. So because of this I've replaced the alternator for a brand new one! Fitted it today and its made zero difference.

Then off and on it would randomly start, and all the time the engine was showing 12v/14v as expected, but the volt gauge in the car showing differently

Now When turning the key in the ignition it doesnt even turn on the ignition and the light that someone had soldered in to blinker when ignition isnt on isn't blinking any more.

Car locks with remote central locking still, all lights are on, everything still works except engaging ignition, a correct voltage reading from radio source, and car wont start

Also the battery light is on but very faint when the car did start

You haven't told us what model you have, so we don't know the battery location, but, assuming it's in the front, check the smaller wires bolted to the battery + clamp are making good contact.

Battery is relocated to the rear with e36 relocation wiring, its a 318is M42 engine

Wires are all tight around the positive ends, both sides

The wires going to the ignition switch aren't getting power, where do those wires come from?

[Brianmoooore]

Red wire bolted to the battery+ clamp goes to the fusebox, bolted to the circuit board by a cap bolt visible through the deck of the fusebox. The end of another red wire is held by this bolt, and this wire goes down the duct underneath the fusebox, and into the cabin.
It then goes across behind the dash to a multi pin rectangular plug and socket, which should be clipped to a bracket half way down the steering column. Another red wire goes on from this plug, and is soldered to the ignition switch. The other main wires from the ignition switch also pass through this plug and socket.

I wiggled wires behind the glovebox and I now have ignition back and the car will start after a couple of tries, battery light still on and low voltage coming from the ignition live behind the radio where does the radio get its 12v from? And I guess I need to check the ground behind there too, see if thats all okay

the car audio loom plugs in behind the glove box in the big white junction box .

Fixed it, was loose positive wires under the fusebox!

Fixed it, was loose positive wires under the fusebox!

As in the cap bolt I mentioned?

Oh yes, like you said
